I believe Sherman is very good, but I don't think it's even a competition. Peterson goes up against Jones, Megatron, AJ, Green, and on and on while Sherman goes up against the second tier guys. To me it's Peterson all day every day. The stats may say Sherman, but the stats don't tell the whole story. If given the choice I want a cb that can lock down the other teams #1 wr as much as a #1 can be locked down that is.
